Why Do I Feel Sick After Eating Eggs?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 22nd, 2026.
Feeling sick after eating eggs typically indicates an egg allergy or intolerance. Egg allergies affect about 1-2% of children and 0.2% of adults, causing symptoms like nausea, vomiting, stomach cramps, or diarrhea within minutes to hours of consumption. Some people develop intolerance later in life, experiencing digestive discomfort without the immune system involvement seen in true allergies. The proteins in egg whites (like ovalbumin) are common culprits, though yolk proteins can also trigger reactions. Other possibilities include contaminated eggs causing food poisoning or existing digestive conditions being aggravated by eggs' high fat content. Keep a food diary to track symptoms and timing, then consult a healthcare provider for proper testing if the pattern continues.
